In the first season (the year 2001) of "Sinterklaasjournaal" the character of Maarten Wansink was called 'Chefpiet' instead of 'Huispiet'. Since 1997, which continued during 2001, actor
Don van Dijke was famous for his role as 'Chefpiet'. This is probably the reason the character of Maarten Wansink was renamed 'Huispiet'.
